AE+ArcSence简单演示三维洪水淹没(无源淹没)

        private void setbasehigh(string height)
        {
            ISceneGraph scenegraph = axSceneControl1.SceneGraph;
            IScene scene = scenegraph.Scene;
            ILayer layer = scene.get_Layer(0);

            IRasterLayer rlayer = layer as IRasterLayer;
            IRasterSurface rsurface = new RasterSurface();
            IRaster raster = (IRaster)rlayer.Raster;

            IRasterBandCollection rasterbands = raster as IRasterBandCollection;
            IRasterBand rasterband = rasterbands.Item(0);
            rsurface.RasterBand = rasterband;
            ISurface surface = rsurface as ISurface;

            ILayerExtensions layerextensions = layer as ILayerExtensions;
            I3DProperties properties = new Raster3DPropertiesClass();
            object p3d;
            for (int i = 0; i < layerextensions.ExtensionCount; i++)
            {
                p3d = layerextensions.get_Extension(i);
                if (p3d != null)
                {
                    properties = (I3DProperties)p3d;
                    break;
                }
            }
            properties.BaseExpressionString = height;
            properties.Apply3DProperties(layer);
            scenegraph = scene.SceneGraph;
            scenegraph.RefreshViewers();
        }

 

简单的思路就是在三维演示上,将计算出来的水淹面利用baseheight属性慢慢抬升,再利用timer控件循环,即可演示三维水淹分析
